I don't believe there's a heavy duty version of the 23-047. It's possible yours was made by a different manufacturer, or maybe just an older version by the same manufacturer. Companies who make this kind of hardware often change the materials used to make it to save on manufacturing costs. Either way, as long as the dimensions match up to our 23-047 then it is probably our best replacement option. |
